Hello,
I created this cosmetic bottle a few years ago and have been continuously improving it since then.
In Korea, the cosmetics industry is constantly evolving, making models like this quite useful. However, in recent years, the materials for glass and the design of droppers in the cosmetics industry have changed significantly, so this model is not used as much anymore.
To explain some improvement methods to the Korean community, I kept the original design while making enhancements.
Have a great day!
